Bostik SL-150™
Bostik SL-150™ is a high compressive strength, self-leveling, cement-based underlayment used to repair, smooth and level concrete as well as existing ceramic, terrazzo or approved plywood subfloors prior to the installation of carpet, vinyl, VCT, laminate, solid and engineered hardwood flooring, ceramic or natural stone. SL-150™ is suitable for thicknesses from feather edge to 1” thick; from 1/2” to 5” thick when mixed as designed with pea gravel. Use on, above or below grade. Use SL-150™ in smaller installations where it may be mixed by hand; or use an underlayment pump to quickly cover large jobs.
